3. Show that the expression 3b - 4 + 6(b-9) is equivalent to the expression 9 (b-6) -4. Show your work. ANSWER ASAP PLZZ

EDITED:

so lets make the question more clear

lets make it like this, if were gonna make 10 = b vv (sorry I meant to say 10, but I said 6 ;-;

3(10) - 4 + 6(10-9) = 30 - 4 + 6 = 26 + 6 = 32

= THIS EQUALS 32

Now lets do 9(b-6) - 4 which will be turned into 9(10-6) - 4 = 36 - 4                          = THIS EQUALS 32

MY ANSWER IS YES (DONT ASK ME WHY IM WRITING IN CAPS (((: )

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
